A central Queensland man says he has invented a device that forces drivers to stop when they approach flooded roads.
Miriam Vale man David Bagnall says he is the first person to create a floating boom gate.
The gate is designed to swivel shut during a flood, closing the road, and floats up and down instead of washing away.
It is only a prototype so far but Mr Bagnall says he hopes someone can take his idea further.
"Council don't have to worry about any crossing they're on, as soon as that water goes over the road the gates will automatically close when they're at an unsafe level," he said.
"They'll see that long before they see the water and they'll have a chance to slow down without hitting the water.
"If they're there they will save lives."
